DETROIT — The political aspirations of musician Kid Rock could be laid bare Tuesday night before thousands of screaming fans when the rocker performs the first of six concerts at a new sports arena in Detroit.

For much of the summer, the Detroit-area native teased a Republican run for the U.S. Senate. Kid Rock’s real name is Robert Ritchie, but it’s not clear which name could appear on the ballot if he runs — something that could make a difference in how well he would do.

“If Robert Ritchie were to submit enough valid signatures to make the ballot and he indicated that he wanted to be listed as ‘Kid Rock’ in some way on the ballot, Bureau of Elections staff would have to research further the question of whether that name would be allowed,” Fred Woodhmans, a spokesman for the Michigan secretary of state’s office told The Associated Press in an email.

Already, two Republicans have declared their candidacies for incumbent Democratic U.S. Sen. Debbie Stabenow’s seat. Stabenow, who easily won re-election in 2006 and 2012, will seek a fourth term and is expected to formally launch her campaign next year.

Kid Rock —who first gained commercial success in the late 1990s with rap rock music but has been more associated with country music in recent years — has not been bashful about his political leanings. He endorsed Republican Mitt Romney for president in 2012 and Republican Donald Trump during the 2016 campaign.

He hinted on social media in July that a website teasing his candidacy for Senate was real. His publicist said Kid Rock will give fans exclusive insight on his political views and aspirations after his first song Tuesday at Little Caesars Arena. The recently completed venue is the new home for the NHL’s Red Wings and the NBA’s Pistons.

But his appearance is expected to be met by protests from a civil rights group.

The National Action Network’s Detroit chapter says Kid Rock’s embrace of the Confederate flag, expletive-laced criticism of NFL quarterback Colin Kaepernick and unabashed support for Trump have no place in Detroit, where about 80 percent of the city’s 680,000 residents are black. Kaepernick, who is black, refused to stand during the national anthem while with the San Francisco 49ers last year in protest of police violence and social injustice.

Kid Rock, who is white, lashed out Monday at National Action Network in a Facebook post, saying politics are behind the threatened protest.

“Pay NO attention to the garbage the extreme left is trying to create!” he wrote. “They are trying to use the old confederate flag (issue), etc. to stir the pot, when we all know none of this would be going on if I were not thinking of running for office.”

Meanwhile, the Detroit Free Press reported Tuesday that Kid Rock denied the newspaper credentials to the show because of a recent column that criticized having the musician as the arena’s opening act.
